Abstract：
OBJECTIVE: Marincolo et al. showed that older adults without limitations in basic activities of daily living at baseline presented with an 11.7% concomitant presence of functional dependence, slow gait speed, and low muscle strength at follow-up. Slow gait speed remains a predictor of dependence in basic activities of daily living. To determine whether low muscle strength and low gait speed increase the risk of disability related to basic activities of daily living in community-dwelling older adults.
METHODS: A longitudinal study (9 years of follow-up) was conducted with 390 older adults who were independent in basic activities of daily living at baseline and answered the Katz Index at follow-up. Associations were determined using Pearson\'s χ2 test with a 5% significance level and logistic regression analysis.
RESULTS: Increases in prevalence between baseline and follow-up were observed for low muscle strength (17.5%-38.2%), slow gait speed (26.0%-81.1%), and functional dependence (10.8%-26.6%). At follow-up, 11.7% of the participants had concomitant functional dependence, slow gait speed, and low muscle strength. Slow gait speed remained a predictor of dependence in basic activities of daily living (odds ratio=1.90; 95% confidence interval=1.06-3.41).
CONCLUSIONS: Slow gait speed is a predictor of functional dependence, constituting an important variable for screening functional decline.

摘要：
目的：Marincolo等人。表明，在基线时，在日常生活的基本活动没有限制的老年人表现出11.7%的伴随存在的功能依赖，缓慢的步态速度，随访时肌肉力量低。缓慢的步态速度仍然是日常生活基本活动依赖的预测指标。确定低肌肉力量和低步态速度是否会增加社区居住的老年人与日常生活基本活动相关的残疾风险。
方法：对390名老年人进行了一项纵向研究（随访9年），这些老年人在基线时独立于基本日常生活活动，并在随访时回答了Katz指数。使用具有5%显著性水平的Pearsonχ2检验和逻辑回归分析确定相关性。
结果：观察到低肌力（17.5%-38.2%）在基线和随访之间的患病率增加，步态速度慢(26.0%-81.1%)，和功能依赖性（10.8%-26.6%）。在后续行动中,11.7%的参与者有伴随的功能依赖，缓慢的步态速度，肌肉力量低。缓慢的步态速度仍然是日常生活基本活动依赖性的预测指标（比值比=1.90；95％置信区间=1.06-3.41）。
结论：缓慢的步态速度是功能依赖性的预测指标，构成筛选功能衰退的重要变量。
